Thank you @chris for your previous comments.

I would appreciate it if you could please have a look at the attached files (gh definition and epw file of Dubai). Question_AryanShahabian_01.rar (975.9 KB)

Could you please check the HVAC, thermostat and natural ventilation settings?

I have set a VAV+reheat. I’m not sure if I have set it correctly. Cooling results are high during winter. Is that because of relatively high humidity of outside air? or I have made a mistake?

These parameters are fixed and I cannot change them: construction of walls and windows as well as glazing ratio.

Other parameters could be altered (e.g. type of HVAC system, air details, heating/cooling details, thermostats, etc.). Current heating and cooling set-points are similar to reference models of climate zone 1-2 from https://www.energycodes.gov/development/commercial/prototype_models

I really appreciate any help you can provide
